Question: see the demand of a brother, the picture I took below.

Special note, some brothers are very careful, the above screenshot said to remove _ finished my answer is for the removal of finished, but does not affect the overall situation, please pay attention.

Answer:

[prepare test data]

Mkdir / oldboy cd / oldboy

Touch stu_102999_1_finished.jpg

Touch stu_102999_2_finished.jpg

Touch stu_102999_3_finished.jpg

Touch stu_102999_4_finished.jpg

Touch stu_102999_5_finished.jpg

Method 1:shell script for loop combined with sed implementation

[check data]

[root@oldboy oldboy] # ll

Total 4

-rw-r--r-- 1 root root 85 Oct 2 12:54 oldboy_modi_file.sh

-rw-r--r-- 1 root root 0 Oct 2 12:50 stu_102999_1_finished.jpg

-rw-r--r-- 1 root root 0 Oct 2 12:50 stu_102999_2_finished.jpg

-rw-r--r-- 1 root root 0 Oct 2 12:50 stu_102999_5_finished.jpg

[development script]

[root@oldboy oldboy] # cat oldboy_modi_file.sh

#! / bin/sh

For file in `ls. / * .jpg`

# shell script for loop, with file as a variable to get the result file name of ls. / * .jpg in turn

Do

Mv $file `echo $file | sed's Universe finishedUniverse G '`

# use the mv command to change the file, and the new file name string concatenation is the focus of this topic.

Done

# Special Tip: through this question, you can learn about the use of the for loop and the use of mv, sed and other commands

[execute script]

[root@oldboy oldboy] # sh oldboy_modi_file.sh

[inspection results]

[root@oldboy oldboy] # ll

-rw-r--r-- 1 root root 0 Oct 2 12:50 stu_102999_5_.jpg

Method 2: partial interception of for loop plus variables in shell script

[root@oldboy oldboy] # ls-l

Total 4

-rw-r--r-- 1 root root 114 Nov 14 00:21 change_file_name.sh

-rw-r--r-- 1 root root 0 Nov 14 00:23 stu_102999_1_finished.jpg

-rw-r--r-- 1 root root 0 Nov 14 00:23 stu_102999_2_finished.jpg

-rw-r--r-- 1 root root 0 Nov 14 00:23 stu_102999_3_finished.jpg

-rw-r--r-- 1 root root 0 Nov 14 00:23 stu_102999_4_finished.jpg

-rw-r--r-- 1 root root 0 Nov 14 00:23 stu_102999_5_finished.jpg

[root@oldboy oldboy] # cat change_file_name.sh

#! / bin/sh

# oldboy QQ:31333741

For file in `ls. / * .jpg`

Do

/ bin/mv $file `echo "${file%finished*} .jpg" `# this is the new method of intercepting variables, which will be discussed in the old boy's shell programming course.

Done

[root@oldboy oldboy] # sh change_file_name.sh

[root@oldboy oldboy] # ls-l

Total 4

-rw-r--r-- 1 root root 114 Nov 14 00:21 change_file_name.sh

-rw-r--r-- 1 root root 0 Nov 14 00:23 stu_102999_1_.jpg

-rw-r--r-- 1 root root 0 Nov 14 00:23 stu_102999_2_.jpg

-rw-r--r-- 1 root root 0 Nov 14 00:23 stu_102999_5_.jpg

Special hint: this script and files are in the same directory.

Method 3: ls combined with awk.
